Audio problem after firmware 2.2.28

I’m having terrible problems with newer recordings only. Older recordings done back in May & June have NO issues. current recordings like my daily recording of Fox news has TERRIBLE chirping during the commercials, almost quits during the actual broadcast-ed news. The commercials are bad enough my wife usually refuses to watch the entire program. We are using the Tablo Internet app. I can watch it on a smart TV thru its roku app & the same program does NOT chirp (I don’t do this very often as using the TV is VERY inconvenient) I’ve also noticed that getting the Tablo to connect to the app without a reboot EVERY time is basically impossible now. It USED to connect very easily & quickly… I haven’t been able to connect without a reboot for weeks now. I’m using 2.2.30
